CLEI
The cement and concrete industry aims to reduce its CO2 emissions, but in Flanders, the lack of primary resources like clays limits the production of cement substitutes that can help achieve this goal. The CLEI project focuses on researching and demonstrating the use of local secondary raw materials to address this challenge.
CLEI investigates the calcination process of selected local secondary raw materials and examines the performance of cement and concrete produced from these calcined materials. This research will not only expand fundamental knowledge about calcination and cementitious reactions but also scale up the technologies through three demonstration projects.
At the Amoras site in Antwerp, 400-500 kilotonnes of dredged sediments are currently landfilled each year. By applying CLEI technologies, it is feasible to produce 400 kilotonnes of supplementary cementitious materials (SCMs) annually with these materials. This could lead to a reduction of 0.5 to 1.5 million tonnes of CO2 emissions per year in the Flemish cement sector.
